Ah, the good news that the Children of Israel received back then. Yea, so the good news they received was a picture of the good news that comes to us, but it's not the same Gospel as we have been given.
The good news they were given was that God was going to bring them out of bondage, slavery to Egypt, and into a land flowing with milk and honey. He was going to bring them out with a mighty hand and outstretched arm.
God did this for them, but the whole time He was doing it for them they kept on grumbling against Him - desiring to be back in Eygpt. The quote from Hebrews was one of those times, specifically the time when they were at Meribah, and drank the water that came from the rock.
While that good news parallels our good news, their good news was about physical bondage, ours is spiritual bondage. Technically, they were in spiritual bondage also, but I think you can understand the difference between the two 'gospels'.
However, the same application can be made. They grumbled at Moses because of the freedom God had given them, much like some grumble at those who preach the Gospel about the freedom Christ has given us.
Some choose not to enter into that rest because their sin of unbelief holds them back from Faith.
What we need to understand was all of that happened to them as examples for us.
There is no distinction. It is the same Greek Word used for different application within scripture. Even in Hebrews 4:3 the distinction is being made between those who believe and those who do not believe enter into God's seventh day Sabbath gospel rest. It is Gods' Word that is being defined therefore as the gospel here. I am not sure why you cannot see this.
It was always about a Spiritual rest. We can not enter into any type of physical rest unless we enter into God's Spiritual rest, Christ Jesus.
Please pay close attention to verse 3. Three things there we need to heed about this rest in which the writer of Hebrews through the Spirit of God is talking about.
One is, we which have believed do enter this rest which is the Gospel that verse 2 is speaking of.
Two it is the same rest in which was available to the the Hebrews in the wilderness, for the word tells us this by alluding to Ps. 95 in verse 3. It is being said in the past tense. He says through the Spirit, "
as He said".
This is compounded by the third thing. The verse's ending statement. The Spirit tells us that the works for this rest were finished from the foundation of the world. The word "if" in the clause "
if they shall enter into my rest" is answered by the word "
although", which speaks of this rest which we who have believe do enter being available to us from the beginning of creation. He says,
"although the works were finished from the foundation of the world."
Now this even more solidified by verse 4. That verse starts with the word "for" which means it is the answer to what was previously said. What it is saying is, when God rested on the Seventh Day; the work He finished included that which was needed for our redemption. It was a done deal. He was foreordained, slain from the foundation of the world 1 pet 1:19,20 and Rev 13:8 say. It was accomplished because His heart was in it, and it's attributes, the Spiritual rest was available.
Now if we did not at least continue to the next verse we would be doing an injustice to our God and to those who happen to be reading this.
Verse 5 starts of with, " In this again". So this begs the question; what again? What is said was done in verse 4. He speaks of the Seventh Day, if we shall enter in His rest.
Please take notice Two separate things being alluded to here. The rest which is the Gospel and the Seventh Day. They are not the same. This verse makes a distinction between the two.
This distinction is brought even more so in verse 9 and 10. And also the question is answered; in what manner of the Seventh Day is he speaking in relation to the rest which is the Gospel?
He says in verse 9, "there remains a Sabbath-keeping for the people of God" That is how speaks again of the Seventh day.
And the distinction between the Gospel rest and Seventh Day is brought out again in verse 10 by the word "also". He says, "He that has entered into His rest ALSO cease from their own works as God did from His". The word "as" makes a direct comparison between our ceasing and God's. God cease from work on the Seventh Day which is the Sabbath so we who have entered into the Gospel Rest also on the Seventh Day cease from our work.
Heb 4:1 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.
Heb 4:2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
Heb 4:3 For we which have believed do enter into rest,
as he said, As I have sworn in my wrath,
if they shall enter into my rest:
although the works were finished from the foundation of the world.
Heb 4:4 For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.
Heb 4:5 And in this again, If they shall enter into my rest.
Heb 4:6 Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
Heb 4:7 Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
Heb 4:8 For if Jesus had given them rest, then would he not afterward have spoken of another day.
Heb 4:9 So there remains a Sabbath-keeping for the people of God.
Footnote: The Greek word translated Sabbath keeeping is sabattismos which is translated rest in the KJV, actually means Sabbath-keeping.
Heb 4:10 For he that is entered into his rest, he
also hath ceased from his own works,
as God did from his.
1Pet 1:19 But with the precious blood of Christ, as of a lamb without blemish and without spot:
1Pet 1:20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
Rev 13:8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
